The invention concerns a method for evaluating therapy effect on a tissue which consists in measuring the mean acoustic attenuation variations based on the frequency by: measuring ultrasounds backscaterred by the tissue before treatment; measuring ultrasounds backscattered by the tissue after treatment. The invention is particularly useful for controlling therapeutic treatments by focused ultrasounds, which induce in the tissues necrotic lesions, caused by sudden temperature increases.
